Effect of Flow Field Optimization of an Asymmetric Multi-Strand Tundish on the Quality Consistency of Cracking Con-Rod Steel.

Cracking con-rod is an advanced high-precision connecting structure based on brittle expansion, breaking and reconnection of steel, to solve the problem of assembly circle missing. High carbon micro-alloyed steel C70S6, as a dominant material for the production of cracking con-rod, has extremely strict requirements on non-metallic inclusions in steel and microstructure stability. Continuous casting tundish plays an important role in removing large-sized inclusions and stabilizing casting quality.

Downregulation of the LncRNA MEG3 Promotes Osteogenic Differentiation of BMSCs and Bone Repairing by Activating Wnt/β-Catenin Signaling Pathway.

Background: Previous studies have demonstrated that long non-coding RNA maternally expressed gene 3 (MEG3) emerged as a key regulator in development and tumorigenesis. This study aims to investigate the function and mechanism of MEG3 in osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and explores the use of MEG3 in skull defects bone repairing.

Methods: Endogenous expression of MEG3 during BMSCs osteogenic differentiation was detected by quantitative real-time polymerase chain reaction (qPCR).

Minocycline promotes posthemorrhagic neurogenesis via M2 microglia polarization via upregulation of the TrkB/BDNF pathway in rats.

Intracerebral hemorrhage (ICH) is a devastating disease worldwide with increasing mortality. The present study investigated whether minocycline was neuroprotective and induced M2 microglial polarization via upregulation of the TrkB/BDNF pathway after ICH. ICH was induced via injection of autologous blood into 150 Sprague-Dawley rats.

EGFRvIII-specific chimeric antigen receptor T cells migrate to and kill tumor deposits infiltrating the brain parenchyma in an invasive xenograft model of glioblastoma.

Glioblastoma (GBM) is the most common primary malignant brain tumor in adults and is uniformly lethal. T-cell-based immunotherapy offers a promising platform for treatment given its potential to specifically target tumor tissue while sparing the normal brain. However, the diffuse and infiltrative nature of these tumors in the brain parenchyma may pose an exceptional hurdle to successful immunotherapy in patients.

Neuroprotective effect of A20 on TNF-induced postischemic apoptosis.

Focal cerebral ischemia causes apoptosis in neural cells during the postischemia period. TNF is critically involved in such neuronal apoptosis mediated by caspase pathways. A20 can inhibit TNF-induced apoptosis in many cell types.

Effect of RNA interference on Gal alpha 1,3 Gal expression in PIEC cells.

Xenotransplantation from pigs to human beings is viewed as a potential solution for the acute organ shortage. However, consequent xenorejection induced by Gal alpha 1,3 Gal (a Gal, Gal antigen) prevents xenotransplantation from clinical application. Thus, the most attracting attempt to prevent xenorejection is the elimination of Gal.

Antiapoptotic effect both in vivo and in vitro of A20 gene when transfected into rat hippocampal neurons.

Aim: To evaluate the antiapoptotic effect of the A20 gene in primary hippocampal neurons both in vivo and in vitro.

Methods: Primary hippocampal neurons in embryonic day 18 (E18) rats were transfected with the A20 gene by using the new Nucleofector electroporation transfection method. We then examined, whether A20-neurons possessed anti-apoptotic abilities after TNF-alpha stimulation in vitro.
